Any news with the last release 257.21 ? At first I had trouble installing it, but with a little modification to the nv4_disp.inf it worked like a charm. More explanations if required ... In fact I still get an error while calling nv4_disp.inf from winnt.sif : at t33 i get an error, "Failed to install one of the core component which may affect driver functionality. The most recent driver that worked will now be restored" Then it asks for reboot (still while installing, after t33), but i got rid of that annoyance by removing all the new words "Reboot" in nv4_disp.inf. Those "Reboot" just appeared in the last 257.21 (and maybe the beta before too), so i figured they were part of the problem, but i always get the first error. Despite of these errors, if i don't interact and let the install complete itself, the driver seems completely installed in windows. So maybe i just bother myself with a very little problem with no consequence, but it stills annoys me that nvidia can't help changing the install package. They also add those lines ... NVSupportAudio = 1 NVSupportNview = 1 NVSupportPhysx = 1
